Hydraulic Filtration

With our filters, things run like clockwork

Filter elements from Filtration Group, which are used in hydraulic systems or in motors for filtration of fluids, maintain a high level of effectiveness even under high pressure and under heavy loads. The filtering capacity of the filters is optimally adapted to any application scenario thanks to a perfect coordination of material properties and design. In addition to performance capacity, filter systems from Filtration Group also succeed because of their long service life, which translates into profitability for any company. Good quality is well worth the price.

Pressure Filters

Designed for use as a full or partial flow filter and for low pressure up to 25/60 bar, medium pressure up to 210 bar and high pressure up to 450 bar, Filtration Group pressure filters are precisely tailored to the requirements of the application as line filters, flange filters and filters in sandwich plate design. Robust housings, flow optimized design and a comprehensive accessory program always offer the right solution for all market requirements.

Suction Filters

Whether installed in front of the pump or, for greater maintenance-friendliness, installed with maintenance indicator in the suction line for easy access from outside, they protect the pump from course impurities. With a wide range of system-compatible elements, the protection of systems and pumps in the fine range of 10 - 25 μm can be guaranteed with our MIC medias or in the coarse range with cleanable wire mesh.

Return Line Filters

All impurities generated in the system and flushed from the hydraulic system are collected by the return line filter, thereby preventing the development of a cycle of contamination through the tank and pump.

Suction Return Line Filters

The combination of a suction filter and a return line filter improves the energy balance compared to a separate system. With the integrated preloaded valve, the pressure in the return line is not reduced, but rather is directly used for suction.

Breather Filters

Corrosion and impact-resistance breather filters are used for impurity-free air supply of tanks. A large selection of system-compatible, changeable filter elements secures the required compatibility with the filter fineness of the hydraulic filters.

Filter Modules

Oil filter module Pi 8300 for use in the primary flow

For gear oil filtration (primary and bypass flow) and for lubrication systems in wind turbines, Filtration Group has developed an innovative, compact oil filter module that increases and sustains the efficiency and service life of the hydraulic and transmission units. The system consists of a filter block with electric motor, gear pump, filter housing with highly efficient 2-stage filter element, pressure relief valve, non-return valve and maintenance indicator. It is available in two version with 110 l/min and 220 l/min volumetric flow. As a complete system in conjunction with an oil cooler, the oil filter module Pi 8300 ensures optimal filtration and cooling of wind power gearboxes and enables low-wear and maintenance-friendly operation.

Oil filter module Pi 8400 for use in bypass filtration

The newly developed filter module sets new standards in off-line filtration and is compatible with the previously used compact systems. The water-absorbing premium filter elements with PulseShieldTM technology filter with a fineness of 3 μm. They reliably separate even finest particles and oil aging products (varnish).

Particle Monitors

With mobile, easy-to-handle measuring devices with variable measuring procedures, impurities in hydraulic fluids can be quickly analyzed and measured. Calibrated for ISO 11171:1999 and evaluated for ISO 4406: 1999 and NAS 1638, the Filtration Group PiC 9100 portable contamination measuring instrument identifies and registers all particles both in suction and pressure mode and reliably displays the absolute number of particles and purity classes. An indispensable instrument for maintenance and service.

Maintenance Indicators

The use of filter elements can only be economically optimal when their dirt holding capacity can be fully utilized without risk. Mechanical or electronic sensors integrated in the filters or installed later respond to continuous changes in the pressure conditions that vary by contamination level and indicate them either via manometer or optical and optical-electrical switches, depending on design. With suction filters, low pressure is registered, while with pressure filters differential pressure is registered and with return line filters the dynamic pressure is registered. The operator can determine the optimal time for changing the filter elements without risk.

Spin-On Cartridges

We offer a wide assortment of spin-on cartridges for hydraulic and lubricating oil filtration. For Filtration Group spin-on cartridges, both conventional cellulose filter media as well as wire mesh and premium fiber glass media are used.

This ensures that the appropriate filtration solution is designed for any application and customer requirement.

Spin-on cartridges with fiberglass media are "long-life" easy-change filters and offer the advantages of our renowned hydraulic elements with the multi-layer design.

Compared to competitors, our "long-life" Spin on Cartridges have an up to 30% longer service life with equivalent filtration efficiency

Spin-on cartridges from Filtration Group are available in different designs, dimensions and pressure levels.

Filter Carts

The high-performance devices for mobile and stationary bypass filtration in hydraulic and lubrication systems guarantee compliance with pre-defined purity classes when using suitable filter elements and can also be used with high-viscosity media. A robust, dirt-sensitive pump ensures a long service life and a wide application spectrum. When pumping into systems and containers, transferring tank contents or unloading system filters during commissioning or after repairs, mobile Filtration Group filter units are an attractive option because of their service-friendly handling and very high dirt collection capacity.

Coalescer Filters

Coalescer filters were specially designed for removing water from hydraulic systems. They run cost-effectively and easily without absorbents: Specially configured filter media collect the small water droplets suspended in the fluid and separate them.
